The phrase, “beauty is in the eye of the beholder” seems especially true for scientists. What we study becomes not only intellectually beautiful, but also literally beautiful: the form is pleasing to the eyes. Appreciation and endearment develops over time as scientists gaze on their subject for hours, days, years. In fact, research by the psychologist Robert Zajonc shows that the more familiar you are with something, the more likely you are to enjoy it.
Researchers have suspected for a few years that neurotransmitters like dopamine play a role in how the immune system functions. But they didn’t know how cells in the immune system would actually used dopamine. A paper published on July 12 of this year shows for the first time that cells in the immune system send dopamine to other cells to trigger them into action. This is just like how neurons use dopamine in the brain! Check out the infographic for a summary of the discovery!
These beautiful little creatures are incredibly skilled at sniffing out mates. The pheromone the females release is called bombykol. Scientists are on the hunt for exactly how this pheromone activates the male brain.
The platypus and the echidna are the only mammals that have the power of electroreception, which means they can sense electrical changes. Check out this new Weird Animal Brain to learn how the platypus uses its bill to catch prey underwater!
Epigenetics change which genes are active and which are inactive. Research over the past few years has shown that these changes are important for protecting the brain from neurodegeneration and injury. A review paper came out on May 18th in the journal Nature Reviews Neuroscience that summarizes this research. Check out the infographic for a description of the review paper.
The brain is one of the most complex and amazing structures in the universe. It allows us to experience the world, feel, remember, and plan for the future. But for at least one organism, the brain is only a means to an end. Learn more in the infographic below!
Sometimes it’s hard to understand why scientists do what they do. Why spend a career studying cells, fungus, or flies? Other than being nerdy and wanting to learn about our world, what’s the point?Continue reading
The octopus almost reaches alien status when it comes to its brain and nervous system. And yet, the differences can help us understand more about the human brain as well as unique solutions nature has come up with for difficult problems like camouflage. Octopuses can see polarized light, but cannot see color. However, their skin changes both color and texture to camouflage with the surroundings.Continue reading
Consider three scenarios. A kid joins a new high school and eats lunch by herself. A recently separated man is alone for the New Year’s Eve countdown. A prisoner becomes aggravated in a solitary confinement cell. The common thread that runs through these disparate experiences is the universal feeling of loneliness.Continue reading
“A barber (who is a man) shaves all and only those men who do not shave themselves. Does he shave himself?”
If you can’t solve the above riddle, don’t worry — nobody can. Continue reading
